我们提出了一个极端的局域化机制，磁场诱导的紧束缚电子在二维结构。这一壮观的现象进行了调查的一大类平铺（周期性，准周期性，或随机）。我们引入Aharonov-Bohm笼，定义为波包最终访问的站点的集合，对于特定的磁通量值，可以有界。最后，我们讨论了量子动力学表现出原始的脉动行为。
We present an extreme localization mechanism induced by a magnetic field for tight-binding electrons in two-dimensional structures. This spectacular phenomenon is investigated for a large class of tilings (periodic, quasiperiodic, or random). We are led to introduce the Aharonov-Bohm cages defined as the set of sites eventually visited by a wavepacket that can, for particular values of the magnetic flux, be bounded. We finally discuss the quantum dynamics which exhibits an original pulsating behaviour.
